LOG LOADING AND UNLOADING GRAPPLE.

Application filed April 29,1921. Serial No. 465,448.

To all whom it may concern:

Be it known that I, O'r'ro Nnwnm, a citizen of the United States, residing at Vallace, in the county of Menominee, State of hflichigan, have invented certain new and useful Improvements in Log Loading and Unloading Grapples; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to new and useful improvements in load handling devices and particularly to devices for handling loads of logs.

In handling pulp wood logs, the logs are loaded on a sled or truck, and a chain passed around the logs and secured thereround. This consumes time. When the logs are to be lifted from the sled or truck and deposited on a car, it is necessary to remove the chain from the logs. This also consumes time, as well as labor. 7

It is the particular object of the present invention to provide a device whereby the use of chains is rendered unnecessary, the logs being loaded on the sled in the usual manner, and when the logs are to be removed and lifted to a car, by means of a crane or derrick, the entire load can be grasped, lifted from the sled, and quickly released when deposited onto the car.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a perspective view of the grap ple, in gripping engagement with a bundle of logs.

Figure 2 is a perspective view of the grapple in open position. 1

l-leferring particularly to the accompanying drawing, 10 and 11 represent a pair of oppositely bowed legs having their upper ends pivotally connected together, as shown at 12 Extending upwardly from each bowed leg, above the pivot 12, is a shank 13 having an eye 1 1 for attachment of the lifting chains 15.

The free end of the bowed leg 10 is bifurcated, as shown at 16, to receive therein the single strand end 17 of the leg 11, when the legs are engaged around the bundle of logs,

as seen on. the drawing, in Figure 1. By

this construction the single strand end is.

prevented from lateral movement, with respect to the end of the other leg, thus firmly and positively gripping and holding the bundle of logs, while being lifted and trans ferred to a car. i

Connected to the bifurcated end 16, and to the eye 14, at "that side of the grapple, is a chain 18 which is adapted to be grasped by the operator on the car, to pull the: legs apart and release the bundle of logs. noted that upon pulling outwardly on the chain 18, the lower end thereof pulls the leg 10 away from the leg 11, while the upper end pulls the eye of the leg 11, and thus swings this latter leg away from the first leg, with the result that both legs are simultaneously withdrawn from beneath the bundie of logs, and the logs permittedto drop onto the car, or logs previously deposited in the car. I

It will be here is thus provided a novel, simple, I

and eflicient device, whereby loads of pulp vided with chain receiving eyes, the lower' end of one of the bowed legs being formed of a single strand, the lower end of the other leg being bifurcated for the reception therein of the end of the first leg whereby the said ends of the legs are prevented from lateralmovementwith respect to each other,

and a releasing chain connected] with the bifurcated legend the eye of the other. leg

for simultaneously moving the legs'aiway from each other to release a bundle of logs. l

In testimony whereof, I affix my signature, in the presence of two witnesses.

I OTTO NEWLIN.
